Hello,
if you are referring to some code ("inspecting the code I think found some
pieces...") please make a reference/link to it.
Tesseract is able to OCR everything that is leptonica able to open or
everything you or programmer is able to convert to leptonica PIX structure
;-)
I did not have a change to test leptonica 1.71, but 1.70 was not able to
open pdf. So the answer to your 1. question is no. leptonica/tesseract do
not support OCR-ing of multi-page PDFs neither single pdf. But it support
multi-page tif.
Regarding your question 2 - I am not aware about any such initiative.
tesseract is OCRing images and pdf is not image format but document format
(e.g. request to OCR pdf is the same as request to OCR odt, doc, docx, html
etc.).
